Which provider do you have for heat pump electricity?

Hello everyone,

we have put our ground source heat pump (with ground collectors) into operation. The brine lines are not yet connected. Currently, we are heating the screed of the lower floor with the heating rod. Afterwards, the upper floor will be heated.

Question: Do both floors really have to be heated individually because the heating rod can no longer manage?

It is a Viessmann Vitocal 200-G

Another question: We have a separate meter for the heat pump. Now I understand that I can choose a separate electricity provider for the heat pump and household electricity. Which provider did you choose for your heat pump electricity? Were there any problems?

Thanks & best regards

Hello, I have also recently been thinking about this (even though we are just shortly before the start of construction): In our case, the heat pump electricity tariff is only 1c / 4c (HT, NT) cheaper than the regular electricity. The additional 7.20 EUR basic monthly fee for the heat tariff is therefore not really worthwhile. Furthermore, I would like to integrate a small photovoltaic system (1.5-2KWP) to support self-consumption. This is not really feasible with two separate electricity tariffs. ==> It is cheaper to run the heat pump on the household electricity tariff.

Hello, a small photovoltaic system (1.5-2kWp) for self-consumption support

If you are already clever enough to rightfully ban the second meter, then calculate again how much sense 2kWp makes... Fill your roof up to a maximum of 10kWp. This has a good effect on the euro/kWp price and the system basically pays for itself (minus business risk). Because whether you pay the electricity supplier or the "solar bank" is the same.

If you are smart enough to ban the second meter (rightly so), then calculate again how much sense 2kWp makes...

I did that ;) Feeding in doesn't really pay off anymore - therefore only self-consumption. And what use is my system if I generate more than I can consume? I might be able to cover some peaks better, but I also often produce too much. More kWp only makes sense with a storage system, which itself is unprofitable again. Furthermore, a small system is exempt from Renewable Energy Act fees and notification requirements, so it also doesn't need a separate meter etc..

I would like to mount the panels on the carport - not much more fits there anyway than the specified 1.5-2KW. Connection and installation costs are also low.

For a 2KW system I'm looking at about 2,000€. You can always upgrade later when the technology (especially the storage or the electricity price) is 2-3 generations ahead.

If I am roughly mistaken somewhere - please let me know ;)

Well, up to 10kWp the Renewable Energy Act doesn't interest you, and even at 2kWp you have to report the system to the grid operator (not register). And I can imagine that a different meter is required.

In winter your system won't bring you anything at all. The larger system more or less pays for itself and the fixed costs (meter & insurance) are probably the same.

That a storage system doesn't make sense, economically I agree with you on that.

Also don't believe that 2 kWp can be realized for 2T€. Or does that include own contributions?
